Specification of Letters Patent.

Application filed October 8,1918. Serial No. 257.413.

To all whom it may concern- Be it known that I, W'nLiAir Konnnnn, a citizen of the United. States of America, residing at Cleveland, in the county of" 5 Cuyahoga andState 0f Ohlo, have invented certain new .and useful Processes and Apparatus for the Oxidation and Reduction of Gaseous Compounds; and I hereby declare the following to be afull, clear, and exact description .of the invention, such. as will enable others skilled in theart tov which it pertains to makeand use it. i V

This invention provides an apparatus for accomplishing the oxidation and reduction of gases orfvapors which are subJect to' reaction by association under proper cond tions. These conditions are as follows: The gases, nozmatter how many in number, must become thoroughly mixed; the temperature of the gases must be raised from norn1al,operating temperatures'to the reaction temperature, which is usuallytheignitmn tempera? ture of the mixture. These conditions must be produced simultaneously, that is, the temperature rise and the mixing of the gases must occur at one and the same time because anj 'gases which are. subject to an oxidation and reduction reaction by association are usually' violently explosive and are extremely dangerous when mixed or associated at other-than, ignition temperature ofthe mixture. It is apparent, therefore, that this apparatus affords a means of associating such gases under proper 'reactingconclitions and at the same time eliminates-all dang from such, reaction.' This apparatus a permits of continuous operation and the products of complete recovery of all the oxidation and reduction.

.Heretofore it hasbeen. attempted to produce reactions of oxidation and reduction by thelassociation of various recovery of the productsof the reaction by mixing the gases at one point and conduct- 46 ing them fron i that point to. another point at which their-temperature would be raised for reaction. During the conducti'onof the inixedjgases from the point'of mixture to the point of, reaction irregularities of flow and irre lairities of p gaseous compounds are almost icertainto re'sultand under these circumstanoes'spontaneous combustion from interinvention.

the oxidation and reduction of wvhch similar reference characters corresponding views, 1 is a section of achamber or conduit 85 chamber 2.- Th

of mixture due to eddy- --h 'perature of the mixture nal friction or thehcat of combinationoftlio gases is most likely to -result.in..a violent and extremely dangerous explosion. There are only a, ifew gases \\'l1lCl1' areeapable of -an oxidation and reduction reaction under these circumstances of separate mixture and reaction points, whereas any gases, no mat-.so

lVhile the illustrations show ,zind the (lescription will be applied to an apparatus for I a controlled mixture of a gaseous carbon compound and a halogen -thereby producing a halogen carbid in the presence of a halogenigacid, I desire it'to be understood that t 1on is not limited thcretm'th' Y v apparatus and-this particulsi r reactipndieing selected merely for purpose ofillustration.

In the accompanying. illustrations, Figure 1 represents across sectiofiwofi' anapparatus suitable for theproductionfof halogen *carbids andFig. 2 represents a section of that! same apparatus on the line 2-5-2 of Fig. 113

In the .accompanying illustrations, in? designate the erro ,1

parts through u through which a carhon'coinpound is passed" 1n the direction of and through conduit or nozzle 10.; 2 represents va chamber or con, duit through= wliich;a halogen is passed-in the dlrection of and through conduits or nozzles 4 in theycasingf' -5 which incloses e conduits :or nozzles 4 are so disposed, withfrefere'nce "to conduit or nozzle 10 thatthe halogen passing-from conduits orhnozzlesf'. completely envelops carbon compound passing from conduit or nOzzlelO an'd'in such a manner that both the halogen and carbon compound are brought toa predetermined proportional mixture at and about.

the point '11; At and about this, point/11, 1m oxidation and reduction'of the combined l} alogen and carbon compound takes place when this mixture or association of gases" p is raised in temperature to the ignition temthe passage of an electric are between the tion temperature the reaction oxidizin electrodes at the point 11. The primary object of this are or other heating medium at the point 11 is .to raise the temperature of i the gaseous mixture. When the temperature of thi mixture has been raised to ignithe, carbon compound and reducing the ha ogen takes place.

An external casing 6 incloses the chamber 3 which. conducts the products of oxidation and reduction to suitable apparatus for its use or for condensation and separation. Electrodes 7 are held in the casi 6 by means of the smiling boxes 8 and said electrodes are connected to a source of current 9.

It is well known that whenever anoxidation takes place it must be accompanied by a corresponding reduction in order to completc vthe reaction and result in stable equilibrium. I use the term oxidation in relaneric sense, and this invention is not limited to theuse of oxygen or oxygen reactions, but, it also includes halogen reactions, and the expression oxidation and reduction -is intended to denote and apply to, and 'for the purposes of this invention it means, any reaction in which there is a combination or dissociation of a. plurality of elements, or a reaction in which one-or more elements .or compounds in combination is oxidized.

3. An a paratus for the oxidation androa. conduit for directing a gas, a plurality o nozzles for directing a' gas -t03a common .point in the flow from said conduit, and
